+# WTFnet Roadmap and Status
+
+This document tracks the planned roadmap alongside the current implementation status.
+
+## Roadmap (from docs/requirement_docs.md)
+
+### v0.1 (MVP)
+- sys: ifaces/ip/route/dns
+- ports: listen/who
+- probe: ping + tcping
+- calc: subnet/contains/overlap
+- basic logging + --json everywhere
+
+### v0.2 (current requirements)
+- dns: query + detect + watch (best-effort)
+- geoip: local Country+ASN mmdb integration
+- http: head/get (HTTP/2 required; HTTP/3 best-effort optional)
+- tls: handshake/verify/cert/alpn
+- neigh: ARP/NDP snapshot
+- discover: mdns + ssdp (bounded)
+- diag: bundle export (zip)
+
+### v0.3 (future upgrades)
+- richer trace output (reverse lookup, per-hop loss)
+- TLS extras: OCSP stapling indicator, more chain parsing
+- ports conns improvements (top talkers / summary)
+- better baseline/diff for system roots
+- smarter "diagnose <domain>" workflow mode
+
+## Current stage
+
+### Implemented
+- Workspace and core crate scaffold.
+- Core data model: command envelope, meta, warnings/errors.
+- Exit code mapping.
+- Logging initialization with text/json formats and optional file output.
+- CLI crate scaffold with global flags and logging config wiring (placeholder `sys ifaces`).
+- Config/env parsing helpers in core (config file + env overrides).
+- Platform trait crate and OS-specific stub crates for Windows/Linux.
+- `sys ifaces` implemented in Windows/Linux providers (via `network-interface`) and wired to CLI.
+- CLI support for `sys ip` and `sys route` (platform routes still OS-specific work).
+- Platform `sys route` implementations (Linux via `/proc/net`, Windows via `route print` parsing).
+- Platform `sys dns` implementations (Linux `/etc/resolv.conf`, Windows `ipconfig /all`) and CLI command.
+- Platform `ports listen/who` best-effort parsing (Linux `/proc/net`, Windows `netstat -ano`).
+- Platform `neigh list` best-effort parsing (Linux `/proc/net/arp`, Windows `arp -a`).
+- Platform `cert roots` implementation via native trust store parsing.
+- CLI commands for `ports listen/who`, `neigh list`, and `cert roots`.
+
+### In progress
+- None.
+
+### Next
+- Start additional platform/feature crates per dependency map.
